Development of a general copper-catalyzed vinylic Finkelstein reaction—application to the synthesis of the C1–C9 fragment of laingolide B

10.1016/j.tet.2016.07.018

The study presents a novel and efficient copper-catalyzed vinylic Finkelstein reaction for the synthesis of various halogenated alkenes, which are important structural elements in pharmaceuticals, agrochemicals, and natural products. The researchers developed a method to convert alkenyl iodides and bromides into their chlorinated and brominated counterparts with high yields and full retention of double bond geometry. This method's broad applicability and mild reaction conditions make it suitable for a range of functionalized substrates. The study demonstrates the potential of this reaction in total synthesis and medicinal chemistry by using it to synthesize the C1–C9 fragment of laingolide B and for the late-stage modification of drug-like molecules. The researchers also explored the extension of this halogen exchange to acetylenic and allenic Finkelstein reactions.
